Multicollector isotope mass spectrometer (MC-ICP-MS) with Triple-Quadrupol MS (3Q-ICP-MS)

同位素信息在化学、生物学、医学、地质学和环境科学的过程研究中发挥着越来越大的作用。同时获取被调查样品中有关微量元素的信息往往会极大地提高信息含量。我们与4个合作伙伴合作申请的系统是多收集器-电感耦合等离子体-质谱仪和三-四-电感耦合等离子体质谱仪的组合，它允许在消除干扰后同时分析同位素比率和痕量元素浓度。样品将以液体(雾化器、层析装置)或固体(激光烧蚀、电子电视耦合)的形式引入。在接下来的几年里，我们将专注于以下主题：(A)通过同位素稀释分析精确定量1%不确定度的固体材料中的元素浓度/制备具有不同元素的标准物质，用于微观和纳米尺度的空间分辨分析(应用领域：植物和动物组织，新材料)(B)与电子电视相结合后纯物质(W，C，Si)中的同位素和微量元素的测定(方法进展)(C)生物浸出过程中细菌/酶调控的过程的研究(同位素系统：S，Fe，Re，Re，(D)建立测定岩浆岩中Hf同位素、碳酸盐岩中锶同位素的常规方法，沉积物输出区分析(含稀土元素的主要和微量元素)以及单矿物(磷灰石、方解石、云母、长石、石榴石、金红石、钛铁矿、锆石)的研究(矿物化学和同位素-B、Li、Lu-Hf、Pb、Rb-Sr、U-Pb)(E)高盐浓度溶液中的同位素和微量元素分析(应用领域采矿、电池生产和回收、环境科学)(同位素系统：B、Li、S、用于调查原料的来源、生产和回收过程中工艺参数的影响以及热力学数据库THEREDA的扩展，该数据库用于计算盐层中正在进行的或潜在的溶解和结晶过程。(F)对植入材料、生物体内的降解、运输和储存过程进行空间解析分析，并在应用富含同位素的起始材料(以铁和镁为基础的可吸收植入合金；同位素系：镁、铁、锗、钕、银)之后对植入材料进行调查

Isotopic information plays an increasing role for the investigation of processes in chemistry, biology, medicine, geology and environmental sciences. A simultaneously obtain information about relevant trace elements in the samples under investigation often improves the information content dramatically. The system we apply for in collaboration with 4 partners is a combination of a Multicollector-ICP-MS and a TripleQuad-ICP-MS which allows for a simultaneous analysis of isotope ratios and concentrations of trace elements after elimination of interferences. Samples will be introduced either as liquids (nebulizer, chromatography unit) or solids (laser ablation, ETV-coupling). During the next years we will focus on the following topics: (a) precise quantification of element concentrations in solid materials with  1 % uncertainty by isotope dilution analysis / Preparation of reference materials wirh different elements for a spatially resolved analysis on the micro- and nanoscale (fields of application:: plant and animal tissues, new materials) (b) Isotope and trace element determination in pure substances (W, C, Si) after coupling with ETV ( method developments) (c) Investigation of bacteriologically/enzymatically regulated processes during bioleaching (Isotopic systems: S, Fe, Re, Os and other PGE) (d) Establishing of routine methods for the determination of Hf-Isotopy in Magmatits, Sr-Isotopy in Carbonatits, the sediment delivery area analysis (main and trace elements with REE), as well as the investigation of single minerals (Apatite, Calcite, Mica, Feldspar, Garnet, Rutile, Titanite, Zircon) (mineral chemistry and isotopy -B, Li, Lu-Hf, Pb, Rb-Sr, U-Pb) (e) Isotope and trace element analysis in solutions with high salt concentrations (application fields mining, battery production and recycling, environmental sciences) (Isotopy systems: B, Li, S, Mg) for the investigation of the provenance of raw materials, the influence of processing parameters during production and recycling, as well as the extension of the thermodynamic datenbase THEREDA, which is applied for calculations of ongoing or potential dissolution and crystallization processes in salt formations. (f) Investigation of implant materials, degradation-, transport- and storage processes in organisms with spatially resoved analysis and after application of isotopically enriched starting materials (resorbable implant alloys based on Fe and Mg; Isotopy systems: Mg, Fe, Gd, Nd, Ag)
